Abstract content
Present low energy experiments do not exclude the existence of a new light ($M<1$ GeV) particle with a small coupling to leptons. It can manifest in the decays of mesons with electron-positron pair(s) in the final state. We present here some results from the search for the very rare $\eta\rightarrow e^+e^-$ decay obtained using the WASA detector at COSY as well as a feasibility study for $\eta\rightarrow\pi^{0}+A'\rightarrow \pi^{0}+e^+e^-$ based on the data collected in the same experiment. The present status of the experimental search for the new light boson will be presented.
